Fruit's good for kids (and grown-ups, too), but fruit drinks aren't. In fact, fruit drinks aren't really more than non-carbonated sodas in sheep's clothing. They contain little fiber and few of the fruit's original nutrients -- especially if they're labeled "juice cocktail," juice-flavored" or "juice drink."
Even 100-percent fruit juice isn't a great choice. Sure, it has vitamins and antioxidants, but one serving can have as much sugar as a candy bar. Some carbonated juice drinks can have up to 6 teaspoons (30 milliliters) of sugar -- more than some sodas -- with food acids that can make short work of a child's teeth. Want to lessen the impact? Mix water and juice to offer the taste while easing the harmful effects.
